True, I did miss that point, but your statement raises another. In that case, you are only supplying a single extra electron from the neutron of the D, so the other K shell vacancy remains unfilled, and will cause a higher level electron to drop into the vacancy releasing an x-ray. Of course, for light elements this will only be a soft x-ray, but for mid-range or heavy atoms this can be quite energetic. Regards, Robin van Spaandonk local asymmetry = temporary success
